Precision Grades & Material Options for Custom Racks
- Medium Carbon Steel: C45 (standard industrial use).
- Alloy Steel: 42CrMo, 20CrMnTi (for high-load, wear-resistant applications).
- Stainless Steel: 304, 316, 17-4PH (for corrosive or sterile environments).
- Engineering Plastics: POM, Nylon, PEEK (for silent, lubrication-free operation).
Engineering Verification
To ensure every custom rack meets your assembly requirements, we provide:
- Pitch Error Reports (Individual and Total Pitch).
- Hardness Testing (for heat-treated parts).
- CMM Inspection Reports (on request for high-precision orders).
Our Customization Workflow
We understand that custom gear rack often involve complex integration challenges. Our workflow is designed to mitigate risk at the design stage and ensure peak performance upon installation.
Step 1: Requirements Communication
We analyze your application constraints. Whether you are designing a high-speed CNC or a delicate medical actuator, we provide expert guidance on module selection (0.1 – 5.0) and material compatibility.
Step 2: Engineering Review & DFM Optimization
We will perform a DFM review of your CAD files or PDF drawings and analyze potential technical issues, such as tool clearance for stepped gear racks or optimal pressure angle design.
Step 3: Adaptive Precision Manufacturing
Depending on your requirements, we deploy the most suitable gear-cutting technology. For requirements reaching ISO / DIN 5 precision, we perform profile grinding post-heat treatment to ensure absolute tooth geometry.
Step 4: Verification & Transparent QC
Every custom rack is verified using Coordinate Measuring Machines (CMM). We provide comprehensive inspection reports covering pitch error, profile deviation, and surface hardness, ensuring that what you receive matches your technical specifications perfectly.
Specialized Application Scenarios
Our focus on small-to-medium modules and gear-grade precision makes us the preferred partner for industries where standard “off-the-shelf” racks fail to perform.
High-Speed Robotics & Pick-and-Place Systems
For 7th-axis robot tracks and automated sorting
Advanced Medical Devices
We specialize in custom racks made from 316L Stainless Steel or High-Performance Plastics (PEEK/POM). for surgical robots, imaging tables, and diagnostic equipment.For instance, the low-noise gear racks required for CT scanner couches produce less than 40 dB of operational noise.
Precision CNC & Laser Cutting Heads
The engagement of rack and pinion achieves the linear feed of the machine table or the positioning movement for laser cutting.
As a professional custom gear and rack manufacturer, we manufacture and deliver the final products in strict accordance with your drawings. Upload your CAD/PDF drawings and receive a detailed technical proposal tailored to your application.
FAQ
We provide high-precision racks up to DIN 5 (ISO Grade 5). By utilizing advanced profile grinding after heat treatment, we ensure minimal cumulative pitch errors, making our racks ideal for high-end CNC machinery and optical positioning systems.
Yes. Generally speaking, small module sizes (high precision, low load capacity) include 1.5, 2, and 2.5.
Absolutely. Using our diverse gear manufacturing processes, we can manufacture internal gear racks and components with shoulders or recessed features.
For high-speed and low-noise requirements, we recommend helical gear racks. For simpler linear movements or cost-sensitive projects, our precision-cut spur racks are a reliable choice.
We offer several options including Induction Hardening, Carburizing, and Nitriding. We can achieve a surface hardness of HRC 55-60.
To maintain manufacturing efficiency while providing engineering-grade precision, our MOQ for custom orders is 5 pieces.
